It seems that the DoD has cancelled their payload (TacSat-1) for the next Falcon 1 launch. As reported in http://spacefellowship.com/News/?p=2835 the launch is scheduled for mid-January 2008.
The launch itself is still paid by the Pentagon, only the payload is removed because TacSat-2 already flew.
